(under subclass 80) Subject matter wherein one of the terminals or electrodes in the liquid element is movable with respect to another electrode or terminal in the element to effect a change in the distance between the electrodes to change the resistance value between the terminals.
(1) Note. For classification here there must be a change in the physical spacing of the electrodes. A mere change in the effective spacing of the electrodes in the resistance element as by adjusting the submersion of tapered electrodes in the liquid resistor is not classified here (see search note below).
SEE OR SEARCH THIS CLASS, SUBCLASS:
86, for a liquid resistor whose liquid level is adjustable on the electrodes. See also (1) Note above.
87+, for a mechanically variable resistor whose contact is adjustably inserted into a nonliquid resistance element.
137, for resistors wherein a plurality of contacts are movable over a single resistance element.
